l Application ledDecemberQl, 1882. (No model.)

To all whom z'tmcy concern Be it known that I, CYRUS CHAMBERS, Jr.,

i a citizen of the United States, residing at the city and'county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Kilns for Drying Bricks, 85o., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which- Figure 1 is a transverse vertical section of ,a drying iiue or kiln' provided with my imej, Fig. 4.

provement.- Fig. 2 is a horizontal sectional view on the line aI b, Fig. 1. .Fig. 3 is a vertical longitudinal section on the line c d, Fig. 1. Fig. 4 i's a plan View of a section of my improved hot-air-dift'usin g iiue shown in the previous figures.` Fig. 5 is a section `on the line This invention is an improvement upon a. certain apparatus for the artificial drying of bricks and other articles, invented by Harvey Gockell, of Chicago, Illinois, for which he `filed an application for Letters Patent on` the 21st day of November, 1882, and of which invention and the Letters Patent that may be issued therefor I am the assignee.

Figs. 1, 2, and 3 of the accompanying drawings show an ordinary brick-drying kiln,

consisting of ala'rge iiue or tunnel, A, built to ascend directly from 4and near the furnace4 to the roof and upper part of the kiln, and to pass off into the stack without having done its full duty-that is to say, without having taken up all the moisture from `the bricks which it is capable of absorbingand thus, while the upper tiers of the bricks become rapidly dried, the lower tiers dry slowly and at the loss of time and atexcessive cost of fuel.

Said Cockell remedies this defect in a large `degree by introducing an auxiliary or diffusA or nearly so, of the main iiue, whereby the heated airis more uniformly diffused within the kiln and among theraw bricks to be dried.4

My invention relates merely to an improvenient in theconstruction of the diffusing-flue F,

and it consistsin making the samein two parts or sides,with an open space between them at the top, .whereby a single central slot, S,is secured along the entire length of the tlue; and it further consists in combining with the said two parts a means for adjusting the width of the slot,so as to limit the quantity of hot air which may pass up through the latter within a given time, as circumstances `may require. One of the means which -I have devised is a transverse bar, N, provided with slots O and bolts or screws X, (see Figs. 4 and 5,) whereby the two sides of the llue may be secured at any desired suitable distance apart. These sides F F are preferablymadeof sheet metal,which by reason of its liexibility, allows of the sufficient adjustment of the opening Sito different widths at various points in its length; or the two sides may be made up of distinct sections, the sev eral openings between which, one successively leading into the other, may be adjusted independently. .By means of this central slotlthe ilue being located along the middle of the bottom of the kiln, below the middle ofthe trucks B) all the hot air arising from furnace D is centrally directed and discharged to ascend and become diffused up between' the bricks upon the trucks, as indicated by the arrows. Then, having become charged with moisture absorbed from the bricks, it passes olfI by way of the stack.

Having thus described my invention, I claim as new anddesire to secure by Letters Patent- 1. In combination with a drying-kiln, the diffusing flue having a continuous central opening therein, substantially as and for the purpose set forth.

2. In a kiln for drying bricks and other articles, the combination, with the main flue, of a slotted diffusing-fine located with reference to the furnace and other parts of the kiln as described, and having devices, substantially IOC as shown and set forth, for regulating the width of the slot or opening leading from the said diffusing-Hue into the main ue.

3. In combination with the main lue of a dryingikilmthe diffusing-Hue composedof two independent parts or sides, whereby, by moving one of said parts to or from the other, the width or" the opening between them may be altered, substantially as shown and set forth.

4. In combination with the two parts or sides of the ilue F, the slotted bar N and boltsX, as and for the purpose specified.

5. The combination of the main ue, the` furnace, the tracks adapted to receive the wheels of trucks, and the diffusing-fine extending over the furnace and provided with a single central slot substantially its entire length, all constructed and operating substantially as and for the purpose described.

In testimony whereof I have hereunto afxed zo my signature this 28th day of November, A. D. 1882.
